IMPROVEMENT IN TUCKERS FOR SEWlNG-MACHlNES.

Specification forming part of Letters Patent No. 132,235, dated October15, 1872.

To all whom it fmay concern:

Be it known that I, JOSEPH H. BEAN, of Cincinnati, in the county ofHamilton and l State of Ohio, have invented a new and ImprovedSewing-Machine Attachment; and I do hereby declare that the following isa full and exact description of the same, reference being had to theaccompanying drawing and to the letters of reference marked thereon.

This invention consists, mainly, in the combination of two adjustablehook-plates with a main stationary plate, the hookplates being soconstructed that both are held, when in the desired position, by asingle set-screw. It further consists in other details of construction,which will be fully described hereinafter.

.In the drawing, Figure 1 represents a plan view of the main plates 5Figs. 2 and 4, plan views of the adjustable hooks; Fig. 3, a plan viewof the shield; Fig. 5, a perspective vievlT of the knob or set-screw;Fig. 6, a plan View of the machine complete; and Fig. 7, a sideelevation of the same.

To enable others skilled' in the art to make and use my invention, Iwill now proceed to describe fully its construction and operation.

A represents the main plate, having the arm c provided with the slot al,and extension c2 providedl with the slots a3 a, as shown. The slots a3a4 are formed by properly cutting the plates and bending the metaldownward out of the way, by which means, also, supports .5 a5 a a6, Fig.7, are formed for the plate to rest upon when in place. Similar supportsa7 ci' are also formed upon the sides of the plate by bending down linesof projecting metal, as shown. The arm a is provided with suitabledistance-lines, regularly numbered each way from a line marked 0, asshown. B represents one of the hookplates, consisting of the hook properb, arm Ill-having the slot b2, and catches b3 b3, as shown. C representsthe other liook plate, consisting of the hook proper c, main portion clhaving the central pin c2 and vertical guides c3 c3, and arm c4 having aiiange, c5, as shown. D represents a threaded knob or set-screw, adaptedto fit a threaded pin, c2, of the hook-plate C. E represents ashield-plate, consisting ofthe main portion c having the slot el, arme2, and guide e3. When these parts are put together the arm b1 of thehook-plate B lies beneath the arm a of the plate A, its

catches b3 b3 serving to hold it in place at one end and still permit itto slide freely. The hook-plate C lies beneath the arm of plate B, itsguides c3 c3 extending up through the slots in plates A and B. It isheld in place by the knob D, and being below the plate B it serves tosupport the inner end or" that also. The shield E is located upon thetop of the plate A, and is also held by the knob, as shown.

The manner of using my improved tucker is as follows: It should besecured upon the ma: chine by means of the gage-screw, with the linemarked 0 upon the plate A in a direct line with the needle. The slots a3a4, designed for the gage-screw, adapt it for useA upon differentmachines. If it is desired to have the tucks meet, place the inner guidec3 in line with figure] upon the main plate A, andthe left hand or outerarm of hook B inline with ligure 8 upon the other side of the line 0upon the plate A. By moving the hook e to figure 2 and hook B to figureet the tucks will be wider and yet meet. Ii' a space is desired betweenthe tucks, move the hook B to the left, leaving hook C stationary. Toput the cloth in the tucker, fold it at the edge so as to about iill thespace between the hooks; then slide it from the left until the rightedge ot' the cloth comes into the right hook; then put the left edge inthe left hook; now adjust the cloth so as to just ll the space evenly;let down the presserfoot, and all is ready. When making the tuck theedge of the goods should be held in the left hand and the Jfolded edgein the right, and the space between the hooks kept f ull and the tucksmade will be perfectly straight and all of one width. When the firsttuck is made turn it to the left, place the edge of it in the hook B,fold the goods under and fill the space between the hooks as before,keeping the space just full, which is easily done, and the work will beperfect and always the same in width. The tuck may be commenced one,two, or three inches from the edge of the dressskirt, by placing theedge of the hem in the hook B and sliding it to the left the desiredwidth. As the gage-hooks B and C are held in place by the setscrew Dwhen the tucker is adjusted to the machine, it remains stationary, andthere is no danger of altering the proper position when the Width of thetuck is changed.

Some ofthe advantages possessed by the construction described are asfollows: By means of the supports of the main plate A it is held upsufficiently for the cloth-plate to relieve the hooks from pressure andpermit them to be readily adjusted. The extension of the hooks beyondthe line of the main plate toward the operator is advantageous becausethe work is much more easily 'placed in the tuclrer than if they wereentirely beneath the main plate. The advantages arising` from thisconstruction will be more readily understood, perhaps, if it isconsidered that in placing the cloth in the tucker a portion of thecloth must be placed in each of the hooks and a portion must pass underthe hook B. The peculiar construction of the hook-plate C, with its arrnc4, instead of a continuation of the hook, enables the device to be usedfor making the nest' tucks. The shield E covers the arrn c4 and preventsthe goods from crowding over the arm after leavin g the needle. rEhedevice is very simple in 1 its construction, and can be made at a smallcost.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the hook-plates B C with the plate A and set-screwD, the plates B U being both held in place upon the plate A by the screwl), as described.

2. The hook-plate U, having the arm c4, with supportingdiange c5arranged in such relation Witnesses:
